Operation
• Summary of Operation
Project Background
• The existing D-Area Powerhouse was built in 1953 and provides
steam to nuclear and industrial activities in F-, H-, and S-Areas. It
is a co-generation facility and provides approximately one half (20
MW) of the Site’s electrical demand.

Project Benefits
• Greenhouse Gas (GHG) emissions reduced by
100,000 tons a year significantly decreasing the
carbon footprint of the SR Site
• Overall annual air emissions rates will decrease
– Particulate Matter
– NOx
– SOx
> 400 tons a year,
> 2,500 tons a year
> 3,500 tons a year
• The amount of river water currently drawn
from the Savannah River will decrease by over
2.8B gal per year
• Sustainable design methods are being used and
energy efficient technologies incorporated

Integrated Project Team
• IPT formed in September 2009
• Included CO, FPM,
representatives of FRs,
Permits, SRNS, technical
representatives as required
• Held meetings every week for
the two-year construction
period
• Provided input to the IMRT
which has met every quarter
6
Truck Off Loading Pad
• First footer poured in
June 2010
• Three off-loading
pads
• Dump time is 6-10
minutes
• The hopper holds
two loads (80T wood
chips)
• 50 trucks per day is
about 1 truck load
every 15 minutes
7
Stacker Reclaimer
• First footer poured
in May 2010
• Receives chips from
the transfer tower
• Holds about 800
truck of wood chips
(32K Tons)
• About a 30 day
supply at 1KT per
day
8
Steam Line Interconnection
• Major Effort &
Coordination with
Ameresco, DOE, & SRNS
• Coordinate interconnection
during planned site steam
outage
• Successfully completed
April 12, 2011
9
13.8 kV Line Tie In
• Worked with SCEG, MOX,
DOE SR
• 18 months of effort
• Ameresco to provide 30%
of the SRS power and 100%
steam from renewable fuel
by February 2012

Summary of First 3 Years of Operation
• After the first three years of operation
– the main facility has provided 5.2 billion pounds of
steam
– 1.3 billion pounds of steam exported to SRS
– 299,400 megawatts of green energy generated to the
site electrical grid ($23.9M)
• This program is a great example of private industry and
the federal government forming a partnership and
working together for success
13
The Challenge for the “Future City Project”
• To design and construct a biomass cogeneration
facility to meet the requirements for providing
100 % of the heating requirements and 40% of
the electrical requirements using “green energy.”
(review other options for providing the energy natural gas for example)
• Develop and implement a safety program;
Establish your IPT
• To work with banking institutions to obtain a
construction loan for the plant (this is not a
federally funded project)
14
The Challenge for the “Future City Project”
• Establish a contract with the local utility to allow
you to “interconnect” with their 115Kv line to
provide power to the city
• Establish contracts with the wood industry to
supply “off spec” wood
• Negotiate an air permit with the SC Department of
Health and Environmental Control (DHEC) to burn a
% of other fuel (like tire derived fuel)
• Look at other additions to electrical security like a
25 MW solar array
